ok so i bought the cobra a week ago and at first it was giving false detection and i was getting really annoyed…once using it for a while it seems to be workin a bit better but i noticed the range isnt too good/// im thinking the product has something wrong with it so im returning it this evening and just wondering if i should stay with the cobra or go for the passport.

none of them really give an explicit range…do any of you know ranges for these? whats better or worse between the 2? also…the passport is about 270 the cobra 180, about 100$ more.
